The value of the angle R in the right triangle PQR is sin⁻¹ 6 / 8
The situation forms a right angle triangle.
<h3>How to find an angle in a right triangle?</h3>
The angle R can be found as follows:
using trigonometric ratios,
sin R = opposite / hypotenuse
Therefore,
opposite sides = 6
hypotenuse = 8
sin R = 6 / 8
R = sin⁻¹ 6 / 8

Convert them into the same form. 1/5 is equal to 2/10, or .2. .21 is clearly slightly bigger than .2
Answer:
r=3
Step-by-step explanation:
if n=10
r=n-7
r=(10)-7
r=3
Answer: Mean: 9
MAD: 46
Step-by-step explanation:
I will show u how to work out the mean
and the mad so u know
MEAN:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
MAD:
1) To find the mean absolute deviation of the data, start by finding the mean of the data set.
2 )Find the sum of the data values, and divide the sum by the number of data values.
3) Find the absolute value of the difference between each data value and the mean: |data value – mean.
